Is there any such thing? It was a trend when I took my master’s program (not in a music field) for graduate students to do annotated lists of orchestral pieces that included unusual or unexpected instrumentation, such as English Horn or C trumpet.
I would be very interested in such a list for harp parts if anyone were aware of any. Although I played in a very good college orchestra, it was quite small, and at the time the harp was not available as a college major in my school.
ASCAP and BMI used to have printed catalogs that gave instrumentations, and with patience you can read through it and mark all the harp parts there. You might be able to find a catalog somewhere, I got the last one ASCAP had years ago.
I hadn’t thought of compiling a list from it, it would take quite some time, and only go up to the year 1975 or so, and does not include a lot of public domain music.
